Isuzu D-Max / Mazda BT-50 (2021–Present) — Bash Plate Set — Engine, Transmission, Transfer Case, Fuel Tank & Lower Control Arms
Maximum Underbody Protection: 5-Plate Coverage from Engine to Lower Control Arms
Combined Weight: 45 kg
The Isuzu D-Max and Mazda BT-50 have earned their stripes as genuinely capable and affordable Australian utes. But as any experienced off-roader will tell you, the factory underbody protection on these vehicles is simply not enough for the tracks most owners want to tackle. This RIVAL 4x4 Set of 5 Aluminium Bash Plates provides the most comprehensive coverage available — from the engine at the front through to the fuel tank and lower control arms at the rear. It's the complete protection solution for D-Max and BT-50 owners who demand maximum confidence on every trail. The full bundle delivers genuine savings over purchasing each plate individually.

What's Protected
- Engine Bash Plate — The D-Max's 3.0-litre diesel engine is a proven performer, but its sump hangs low and exposed. A single rock strike can crack the oil pan, draining oil and seizing the engine in minutes. On a remote outback track, that's a recovery operation that costs thousands. This plate provides comprehensive engine underside protection.
- Transmission Bash Plate — The automatic or manual gearbox casing sits behind the engine, vulnerable to rocks and ruts that pass under the engine plate. A damaged gearbox housing leaks fluid and results in complete loss of drive. This plate shields the entire transmission assembly.
- Transfer Case Bash Plate — The transfer case is the centre of the D-Max's 4WD system, distributing power between front and rear axles. It's mounted centrally and low, making it an easy target for trail rocks. A compromised transfer case means no four-wheel drive in terrain that demands it.
- Fuel Tank Bash Plate — The fuel tank stretches beneath the rear section of the vehicle, carrying your entire fuel supply. In remote Australia, a punctured fuel tank is far more than an inconvenience — it's a genuine emergency. This plate ensures your fuel supply is protected on every kilometre of unsealed road.
- Lower Control Arms Bash Plate — The lower control arms are the suspension components most exposed to lateral rock strikes. A bent or cracked arm throws the wheel alignment out, causes rapid tyre wear, and compromises handling and steering. These plates shield the arms from side impacts on rocky tracks and narrow trails.

Why Choose Aluminium Over Steel?
- GVM-Friendly: The D-Max and BT-50 have tight GVM limits. Five aluminium plates at 45 kg leaves significantly more capacity for gear than a steel equivalent that could weigh 70+ kg.
- Corrosion Resistance: Aluminium naturally resists rust — essential for utes that regularly cross rivers, drive beaches, and operate in tropical humidity across northern Australia.
- Impact Absorption: Aluminium's controlled flex distributes impact energy across the plate, reducing stress on the D-Max's chassis and mounting points.
- Smart Weight Management: 6mm aluminium alloy provides serious protection without pushing your ute's payload capacity to the limit.

Built for Australian Conditions
The D-Max and BT-50 are workhorses across Australia — from the fishing tracks of Arnhem Land to the logging roads of Gippsland, from Cape York's infamous tracks to the corrugated gibber of the Birdsville Track. These vehicles see it all, and so do their undersides. RIVAL 4x4 bash plates are engineered for this relentless daily punishment. The corrosion-resistant powder coat handles salt spray, tropical downpours, red dust, and everything in between. Ventilated design keeps engine bay and drivetrain temperatures optimal during slow-speed work in summer heat.
